IMPROVEMENT IN CARPET-SWEEPERS. i

p Specification forming part of Letters Patent No. 140,293, dated June 24,1873, application filed February 8, 1873.

.To all 'whom it may concern:-

Be it known that I, WIL'LIAAI MILLER, of Boston, in the county of Suiolk and State of Massachusetts, have invented certain Improvements in CarpetSweepers, of which the following is a specification: y

Figure l of the accompanying drawing is a top view, and Fig. 2 is a side View, of my im- Fig. 3 is a central vertical longitudinal section through the box of ,the sweeper.

',lhe present invention relates to certain new Aand useful improvements in the class of carpet-sweepers whose brush-is revolved by the opera-tion of pulleysv and connecting-bands;

and has i. fou its principal. objecutheNmore eective operation of the sweeper. v

To this end it consists in the combnatio and arrangement of parts as I will now proceed to describe.

In the accompanying drawings, a represents the body or box of a carpet-sweeper whose bottom a is closed on the forward part, and left open rearward, to allow the action of a brush, b, connected with and revolved by an axle, c, that extends transversely across the `interior and lthrough the rear ends of the sides of the box a.. Connected with the `bottom'a at the rear, and slopingupward a sufficient distance, and at a proper angle toward-the front,

is a transverse strip or guide d, for the purpose of directing the ldirt into and prevent its falling back from'the box. tion of the front of the box ct is hinged to the upper part, and forms an outward swinging lid, e, that is held or 'released by hooks f pivote'd to the sides of the box, that engage with or are disengaged from pins g connected with the ends of the lid e or the lid e, which 1 is for the purpose of, allowing the removal of the dirt, may, if desired, be otherwise ar ranged ,to open and shut, and be fastened or released. Connected with the axle o so as not to interfere with its rotation, and yet hold the same, and extending upward either on the outside or inside of each side ofthe box a is a rod, h, formed on the top with screwthreads and passing through horizontal plates' or bearings t' i', one above the other, leaving a space between. and attached to the top ofthe The lower por-l box a.. Turning on thescrew end of the rod h, above the plate 1J, is a thumb-screw, k, andV in the space between the plates t t" is a thumb-screw, k', that also turns on the screw end 0f the rod h., so that by loosening the thumb-screw k, and turning the thumbscrews k', the rod h, and consequently the axle and brush connected with them, are raised or lowered, and the brush adjusted as desired. Connected with the ends of the axle c, so as to turn on them, are the ends of lever-arms j, that extend forward on each` side of and around the front of the box, where they connect at the center with the rear end of a handle, l, which is provided at the forward and. rear ends with suitable slidingaxles m m, each formed with a screw-collar or socket, in which thumb-screws m engage to release or hold the axles and allow of their proper act justment on the handle l.' Held by and turning on the forward axle m is a pulley, u, provided with a handle, a. The pulley a con nects by a belt, n, with a small pulley, o, that turns on the axle m and connects by a shaft, o', with a larger pulley, o, that connects by a belt, p, withxya pulley, p', attached to the main axle c. part of the top of ,the box a, so as to be extended beyond the front or turned back over the top, is a catch, r, that, when extended, allows the box to be lifted by the handle and carried from one part of the room to another, without tipping.

By the above description, reference being had to the drawings, it will be seen that by.

turning the forward pulley n the several pul leys o, o, and p are by their connecting-bands operated, and the brush b revolved, thus throwing the dirt up the inclined-guide d into the forward part of the box, from which it is removed by unfastening the hooks f from the pins g and opening the lid e. When it is de sired to lift the handle l to remove the box from one position to the otherfor to turn it up so as to be out of the way when the sweeper is not in use, it will be seen that the arms j connected with and turning on the same axle with the axle-pulley 19', and being aixed to the handle allows the latter, and consequently the box, to be raised or lowered, without vary Pivoted on the forward ing the tension ol' the connecting-bainis n" and j). l lt will alsol be observed that'. any wear of the brush may be taken up, or its positiouin regard to the carpet altered, as desired, by means ofthe screw-rods hvconneeted with the bruslraxle c, and opera-ted by the thumbserews 7c k, as shown and above described.

Having thus fully described my improvements, what I claim as my invention, and desire to have .secured to me by Letters Patent, 1sf l. The screw-rods h, provided with thumbfscrews 7s 7i", and held in bearings ii', in combination with the axle e of the brush Insubstantially as described, for the purpose specied.

2. The adjustable axles m m', provided'with pulleys n o o, in combination with the handle andaxles c, having the pulley p, substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification n the presence ot tw'o subscribing witnesses,

VILLIAM MILLER.
